It isn't caliber limited that I'm aware of, but it is velocity limited at 4,000 fps. They name some calibers at this speed (.22-250), so I think it is calibers CAPABLE of shooting that fast. They also do not allow tracer, steel core, armor piercing, or bird shot.
You can fire up to .50 caliber. There is no round or time limit unless there are people waiting and then it's one hour.
No steel or aluminum case. No green tipped or armor penetrating.
I'm sorry I don't know the caliber limit, I don't think there's a round limit, but I know you can reserve a lane for the day they said.
